Purpose: To investigate the MRI and arthroscopic findings of osteochondral lesion of the talus which looked normal on plane radiography. Materials and methods: We investigated the MRI and arthroscopic findings of seven osteochondral lesions in which there were no abnormal finding on plane radiography and no cystic changes on MRI. Average age was 31 years(range, 19-43 years). Arthroscopic findings were classified according to the Ferkel's criteria. Results: History of injury was reported in all cases and the average duration from injury to presentation was 4 years and 4 months. Low signal change in T1WI was found in 6 of 7 lesions, no signal change in 1 case. Low signal change in T2WI was found in 4, no signal change in 3. 6 STIR images were obtained. High signal change was found in 3, no signal change in 2 and intermediate signal change was in 1. Arthroscopic grading was A in 1, C in 1, D in 2 , E in 1 and F in 2. We could not find any correlation between the findings on MRI and arthroscopic examination. Conclusion: We suggest arthroscopic examination is needed for accurate diagnosis of the osteochondral lesions of the talus which looked normal on plane radiography, because they have various MRl findings and high likelihood of existence of unstable cartilage lesions.

Purpose: To investigate the relationship between classification based on simple radiographic findings and arthroscopic findings of the cartilage lesions in medial degenerative arthritis of the ankle joint. Materials and Methods: We studied 41 ankles of 36 patients with asymmetrical narrowing of the medial joint space. Degenerative arthritis following fracture and those with generalized arthritic disease were excluded, but those with a history of ankle sprain were included. Standing radiographs of all patients were graded according to the Takakura classification and the Kellgren-Lawrence (K/L) classification. Arthroscopic findings were classified according to the depth, width, and anteroposterior dimension of articular cartilage damage. Results: According to the Takakura classification, 29 ankles were classified as stage II, 7 cases as stage IIIA and 2 cases as stage IIIB. According to our classification of arthroscopic findings of 29 ankles in stage II, 1 ankle was graded as Grade I, 3 ankles as grade II, 10 ankles as grade III, and 15 ankles as grade IV. Spearman correlation coefficient between Takakura classification and arthroscopic classification was 0.342 (P=0.028), and coefficient between K/L classification and arthroscopic classification was 0.480 (P=0.001). Conclusion: Degenerative changes of the articular cartilage are more advanced than radiographic findings in many patients with ankle degenerative arthritis with asymmetrical narrowing of medial joint space. Therefore, we conclude that more aggressive effort should be made for correct diagnosis and treatment of degenerative arthritis.

Purpose: Urgent diagnosis and treatment of the septic arthritis is required. The purpose of this study is to review to correlate preoperative MRI findings with arthroscopic findings in septic arthritis of the glenohumeral joint. Materials and Methods: Eleven patients with acute septic arthritis of the glenohumeral joint were treated with combination of arthroscopic lavage, debridement, and systemic antibiotics. The arthroscopic staging of infection was made based on the modified criteria of $G\"{a}chter$ and five major findings of MRI were marked in each stage of septic shoulder. Results: Bone and cartilage erosion was the end stage finding and two patients with all five positive findings had failed with arthroscopic treatment. Reactive bone marrow edema was evident in the greater tuberosity. Joint effusion, synovial thickening and soft tissue edema were rather non-specific finding and presented in all stages of septic shoulder. Conclusion: Diffuse marrow edema with metaphyseal cyst formation in the preoperative MRI implied advanced stage of septic arthritis, which may fail with arthroscopic debridement.

Purpose: We report our results of arthroscopic treatment of symptomatic avulsion fracture of the malleolus in chronic ankle pain, and also analyzed the clinical and radiological features for evaluating the good candidate for arthroscopic treatment. Materials and Methods: Fourteen patients who were diagnosed with intra-articular avulsion fractures of the malleolus received arthroscopic surgery and were followed up for at least a year. The clinical and radiological characters including MRI and arthroscopic findings were reviewed. Clinical assessments were done according to the AOFAS score system. Results: There was a history of inversion type of the injury in most cases and local tenderness of lesion site was a unique. MRI study showed thickened anterior talofibular ligament (ATFL) in 8 cases (57%) and discontinued ATFL in 3 cases (21%). Enhanced signal surrounding soft tissue corresponding to synovial inflammation and impingement was found in 12 cases (86%). Preoperative score of all patients were $74.0{\pm}5.5$, which improved to $89.3{\pm}6.7$ at the follow-up after the treatment (P<0.001). Conclusion: Most patients had history of injury and localized tenderness in the area coinciding with radiological findings. Thickened ATFL and contrast enhancement around the ossicle were frequently found. Symptomatic avulsion fractures of the malleolus associated with the clinical and radiological findings above could be a good candidate for arthroscopic treatment.

Purpose: The purpose of this study was to compare the preoperative magnetic resonance image (MRI) findings with postoperative arthroscopic findings on meniscus injury with anterior cruciate ligament (ACL) rupture. Materials and Methods: We reviewed MRI images and arthroscopic findings of 225 patients treated by ACL reconstruction due to rupture, from February 2001 to November 2010. There were 154 cases of meniscus tear in arthroscopic findings. We examined the sensitivity for detecting meniscal tears varied with the presence of a rupture of the ACL, with the location of the tear within the meniscus, and among configurations of meniscal tears. Results: In the presence of a rupture of the ACL, the sensitivity of MRI was 0.88 for medial meniscal tears and 0.69 for lateral meniscal tears. And sensitivity of MRI was lowest in posterior horn and peripheral portion tears in lateral meniscus injury accompanying ACL rupture, sensitivity was low in anterior horn and flap shape tears in medial meniscus injury accompanying ACL rupture. Conclusion: In Meniscus injury with ACL rupture, a special attention shoulder given to the posterior horn and peripheral portion injury in lateral meniscus during arthroscopic surgery due to difficulty in detecting on MRI.

Purpose : We observed usability of allograft by evaluating the clinical results, second look arthroscopic and histologic findings at last follow up after anterior cruciate ligament(ACL) reconstruction using by fresh frozen Achilles allograft. Materials and Methods : We analyzed in 58 patients(59 cases) by subjective and objective parameters, Telos stress arthrometer and Modified Feagin Scoring System. The average age and follow up period was 25 years(ranging from 18 to 49 years), and 15 months(ranging from 12 to 19 months). Among them we studied second look arthroscopic and histologic findings in 16 patients. Results : The mean Lysholm Score wits improved from 60 to 88.2 as well the anterior translation was improved from 7.1 min to 2.3mm at last follow up. The second look arthroscopic findings were close to normal in ligament thickness, tension and showed revasculization at the holly attachment site. Light microscope(LM) findings showed dense cellularity like a normal ligament. In electron microscope(EM) collagen fibrils showed parallel arrangement longitudinally and unimodal pattern diameter close to normal tissue in the transverse section. Conclusion : We think that the fresh frozen Achilles allograft is a good substitution of autograft in cruciate ligament reconstruction.

Purpose: The purpose of this study is to evaluate the accuracy of magnetic resonance imaging (MRI) in the diagnosis of acute anterior cruciate ligament (ACL) injury and its tear pattern in comparison with arthroscopic finding. Materials and Methods: Sixty consecutive patients with acute ACL injury were taken NRI followed by arthroscopic examination between January 2002 and June 2004. MRI findings were reviewed according to the presence of ACL discontinuity, diffuse swelling or thickening, focal edema, collapse on distal end, and any combined tear. The pathologic findings were then confirmed arthroscopically. The diagnostic accuracy of MRI on ACL tear pattern was analyzed by obtaining its positive predictive value. Results: All fifty two cases with presence of discontinuity on MRI showed ACL rupture arthroscopically. The location of ACL tear, diffuse swelling and focal edema on MRI also corresponded with arthroscopic findings respectively. However, the diagnostic accuracy of MRI was relatively lower in the presence of other ACL patterns such as collapses and combined tear. Conclusion: Preoperative MRI findings seem to be in accordance with arthroscopic findings and is significantly accurate in detection of location and diffuse swelling and focal edema of ACL tear.

Purpose: This study examined the effects of therapeutic massage (TMP) and home exercise program (HEP) on pain, range of motion (ROM), depression, and quality of life (QOL) after arthroscopic rotator cuff repair in middle-aged women. Methods: Nineteen middle-aged women who underwent arthroscopic rotator cuff repair were enrolled in the study. All subjects were assigned randomly to the experimental group (n=9) or the control group (n=10). The subjects in both groups performed HEP for 30 minutes, three times per day, for eight weeks. The subjects in the experimental group also performed HEP, with TMP being performed for 30 minutes, 16 sessions for eight weeks. All subjects were evaluated with a visual analogue scale (VAS), shoulder ROM, self-rating depression scale (SDS), and Korean brief version of WHO quality of life scale (WHOQOL-BREF). A paired t-test was performed to test the significant differences between before and after the intervention. An independent t-test was conducted to test the significant differences between the groups. Results: Following the intervention, both groups showed significant differences than before the intervention in the VAS, shoulder ROM, SDS, and WHOQOL-BREF (p<0.05). There were significant differences in the ROM of shoulder flexion, SDS, and WHOQOL-BREF between the groups (p<0.05). Conclusion: These findings suggest that intensive TMP is an effective method for improving shoulder flexion mobility, depressive symptom, and QOL in middle-aged women after arthroscopic rotator cuff repair.
